First of all, thanks for maintaining this crate 🚀 I wanted to check something with people that might be more familiar with inner workings of this crate (or duckdb for that matter): I have a use-case where I export data from Snowflake to S3, and then ingest that data into in-memory duckdb, using ducdkb-rs crate. Everything is fine and all, but I am not sure what is the best way to handle scenario where there is no data in original Snowflake table: in that case Snowflake does not create empty parquet file, it doesn't do anything really. If that happens, currently I get an Error result, and I figured out from error messages that it it kinda looks like something this f-on should return true for: fn is_http_404_error(msg: &str) -> bool { let msg = msg.to_lowercase(); msg.starts_with("http error") && msg.ends_with("404 (not found).") } As far as I remember, the actual instance is duckdb::Error::DuckDBFailure, not sure about ErrorCode though. I have a test suite that started failin
